| 8.6.1 | Scientific method

Network troubleshooting is a systematic process applied to solving a problem on a network. A good way to get started would be to use the Dartmouth Design Matrix that was used in the network design phase of the course. It is a very good tool for establishing a systematic analysis technique for troubleshooting. Another technique for troubleshooting is the scientific method. In the first list is the actual scientific method and the second list shows the scientific method specifically pointed at troubleshooting.
Scientific Method:
1. Observe some aspect of the universe.
2. Invent a theory that is consistent with what you have observed.
3. Use the theory to make predictions.
4. Test those predictions by experiments or further observations.
5. Modify the theory in the light of your results.
6. Go to step 3.
Scientific Method for Troubleshooting:
1. Identify network/user problem.
2. Gather data about network/user problem.
3. Analyze data to come up with a possible solution to the problem.
4. Implement solution to network to attempt correction to the system.
5. If the problem isn't resolved, undo previous changes and modify data.
6. Go to step 3
